Iran and six world powers known as the P5+1 (USA, Germany, France, the United Kingdom, China and Russia) ) reached a historic nuclear deal on July 14, 2015, that limited Iran's nuclear program and enhanced monitoring in exchange for relief from nuclear sanctions. Prior to that, Iran had been engaged in efforts to acquire the capability to build nuclear weapons for more than two decades. Although it remained uncertain whether Tehran would have made the final decision to build nuclear weapons, it had developed a range of technologies, including uranium enrichment, warhead design, and delivery systems, that would give it this option in a relatively short time frame. Tehran maintains that its nuclear activities are entirely peaceful.
What follows is a chronological recount of the most significant developments in Iran’s nuclear program, international efforts to negotiate a settlement to address this controversial issue, and implementation of the agreement reached by Iran and the P5+1 on July 14, 2015.
November 1967: Iran’s first nuclear reactor, the U.S. supplied five-megawatt Tehran Research Reactor (TRR) goes critical. It operates on uranium enriched to about 93 percent (it is converted to run on 20 percent in 1993,) which the United States also supplies.
February 1970: The Iranian parliament ratifies the nuclear Nonproliferation Treaty (NPT).
1974: Shah Reza Pahlavi establishes the Atomic Energy Organization of Iran (AEOI) and announces plans to generate about 23,000 megawatts of energy over 20 years, including the construction of 23 nuclear power plants and the development of a full nuclear fuel cycle.
1979: The Iranian Revolution and the seizure of the U.S. embassy in Tehran result in a severing of U.S.-Iranian ties and damages Iran’s relationship with the West. Iranian nuclear projects are halted.
January 19, 1984: The U.S. Department of State adds Iran to its list of state sponsors of terrorism, effectively imposing sweeping sanctions on Tehran.
1987: Iran acquires technical schematics for building a P-1 centrifuge from the Abdul Qadeer Khan network.
1992: Congress passes the Iran-Iraq Arms Nonproliferation Act of 1992, which prohibits the transfer of controlled goods or technology that might contribute “knowingly and materially” to Iran’s proliferation of advanced conventional weapons.
1993: Conversion of the TRR is completed by Argentina’s Applied Research Institute. It now runs on fuel enriched to just less than 20 percent, 115 kilograms of which is provided by Argentina; the contract for the conversion was signed in 1987.
August 5, 1996: The U.S. Congress passes the Iran-Libya Sanctions Act, also known as the Iran Sanctions Act, that penalizes foreign and U.S. investment exceeding $20 million in Iran’s energy sector in one year.
August 2002: The National Council of Resistance on Iran, the political wing of the terrorist organization Mujahideen-e Khalq (MeK), holds a press conference and declares Iran has built nuclear facilities near Natanz and Arak.
September 12, 2003: The International Atomic Energy Agency (IAEA) Board of Governors adopts a resolution calling for Iran to suspend all enrichment – and reprocessing- related activities. The resolution requires Iran to declare all material relevant to its uranium-enrichment program and allow IAEA inspectors to conduct environmental sampling at any location. The resolution requires Iran to meet its conditions by October 31st 2003.
October 21, 2003: Iran agrees to meet IAEA demands by the October 31st deadline. In a deal struck between Iran and European foreign ministers, Iran agrees to suspend its uranium–enrichment activities and ratify an additional protocol requiring Iran to provide an expanded declaration of its nuclear activities and granting the IAEA broader rights of access to sites in the country.
June 18, 2004: The IAEA rebukes Iran for failing to cooperate with IAEA inspectors. Iran responds by refusing to suspend enrichment-related activities as it had previously pledged.
November 14, 2004: Iran notifies the IAEA that it will suspend enrichment-related activities following talks with France, Germany, and the United Kingdom. According to the so-called Paris Agreement, Iran would maintain the suspension for the duration of talks among the four countries. As a result, the IAEA Board of Governors decides not to refer Tehran to the UN Security Council.
February 27, 2005: Russia and Iran conclude a nuclear fuel supply agreement in which Russia would provide fuel for the Bushehr reactor it is constructing and Iran would return the spent nuclear fuel to Russia. The arrangement is aimed at preventing Iran from extracting plutonium for nuclear weapons from the spent nuclear fuel.
August 8, 2005: Iran begins producing uranium hexafluoride at its Isfahan facility. As a result, France, Germany, and the United Kingdom halt negotiations with Tehran.
September 24, 2005: The IAEA adopts a resolution finding Iran in noncompliance with its safeguards agreement by a vote of 22-1 with 12 members abstaining. The resolution says that the nature of Iran’s nuclear activities and the lack of assurance in their peaceful nature fall under the purview of the UN Security Council, paving the way for a future referral.
February 4, 2006: A special meeting of the IAEA Board of Governors refers Iran to the UN Security Council. The resolution “deems it necessary for Iran to” suspend its enrichment-related activities, reconsider the construction of the Arak heavy-water reactor, ratify the additional protocol to its safeguards agreement, and fully cooperate with the agency’s investigation.
February 6, 2006: Iran tells the IAEA that it will stop voluntarily implementing the additional protocol and other non-legally binding inspection procedures.
April 11, 2006: Iran announces that it has enriched uranium for the first time. The uranium enriched to about 3.5 percent was produced at the Natanz pilot enrichment plant.
June 6, 2006: China, France, Germany, Russia the United Kingdom, and the United Sates (the P5+1, referring to the five permanent members of the UN Security Council and Germany) propose a framework agreement to Iran offering incentives for Iran to halt its enrichment program for an indefinite period of time.
July 31, 2006: The UN Security Council adopts Resolution 1696, making the IAEA’s calls for Iran to suspend enrichment –related and reprocessing activities legally binding for the first time.
August 22, 2006: Iran delivers a response to the P5+1 proposal, rejecting the requirement to suspend enrichment but declaring that the package contained “elements which may be useful for a constructive approach.”
December 23, 2006: The UN Security Council unanimously adopts Resolution 1737, imposing sanctions on Iran for its failure to suspend its enrichment-related activities. The sanctions prohibit countries from transferring sensitive nuclear- and missile-related technology to Iran and require that all countries freeze the assets of ten Iranian organizations and twelve individuals for their involvement in Iran’s nuclear and missile programs.
March 24, 2007: The UN Security Council unanimously adopts Resolution 1747 in response to Iran’s continued failure to comply with the council’s demand to suspend uranium enrichment.

December 3, 2007: The United States publicly releases an unclassified summary of a new National Intelligence Estimate report on Iran’s nuclear program. The NIE says that the intelligence community judged “with high confidence” that Iran halted its nuclear weapons program in the fall of 2003 and assessed with moderate confidence that the program had not resumed as of mid-2007. The report defines Iran’s nuclear weapons program as “design and weaponization work” as well as clandestine uranium conversion and enrichment. The NIE also said that Iran was believed to be technically capable of producing enough highly enriched uranium for a nuclear weapon between 2010 and 2015.
March 3, 2008: The UN Security Council passes Resolution 1803, further broadening sanctions on Iran. It requires increased efforts on the part of member states to prevent Iran from acquiring sensitive nuclear or missile technology and adds 13 persons and seven entities to the UN blacklist.
June 14, 2008: The P5+1 present a new comprehensive proposal to Iran updating its 2006 incentives package. The new proposal maintained the same basic framework as the one in 2006, but highlighted an initial “freeze-for-freeze” process wherein Iran would halt any expansion of its enrichment activities while the UN Security Council agreed not to impose additional sanctions.
February 3, 2009: Iran announces that it successfully carried out its first satellite launch, raising international concerns that Iran’s ballistic missile potential was growing.
April 8, 2009: Following an Iran policy review by the new Obama administration, the United States announces that it would participate fully in the P5+1 talks with Iran, a departure from the previous administration’s policy requiring Iran to meet UN demands first.
June 12, 2009: Iran holds presidential elections. Incumbent Mahmoud Ahmadinejad is declared the winner amid many indications that the election was rigged. This sparks weeks of protests within Iran and delays diplomatic efforts to address Iran’s nuclear program.
September 25, 2009: United States President Barack Obama, British Prime Minister Gordon Brown, and French President Nicolas Sarkozy announced that Iran has been constructing a secret, second uranium-enrichment facility, Fordow, in the mountains near the holy city of Qom. IAEA spokesman Marc Vidricaire said that Iran informed the agency September 21 about the existence of the facility, but U.S. intelligence officials said Iran offered the confirmation only after learning that it had been discovered by the United States.
October 1, 2009: The P5+1 and Iran agree “in principle” to a U.S.-initiated, IAEA-backed, proposal to fuel the TRR. The proposal entails Iran exporting the majority of its 3.5 percent enriched Uranium in return for 20 percent-enriched uranium fuel for the TRR, which has exhausted much of its supply. This agreement was later met with domestic political opposition in Iran, resulting in attempts by Tehran to change the terms of the “fuel swap.”
February 9, 2010: Iran begins the process of producing 20 percent enriched uranium, allegedly for the TRR.
May 17, 2010: Brazil, Iran, and Turkey issue a joint declaration attempting to resuscitate the TRR fuel-swap proposal. In the declaration, Iran agrees to ship 1,200 kilograms of 3.5 percent enriched uranium to Turkey in return for TRR fuel from France and Russia. France, Russia, and the United States reject the arrangement, citing Iran’s larger stockpile of 3.5 percent-enriched uranium and the failure of the declaration to address Iran’s enrichment to 20 percent.
June 9, 2010: The UN Security Council adopts Resolution 1929, significantly expanding sanctions against Iran. In addition to tightening proliferation-related sanctions and banning Iran from carrying out nuclear-capable ballistic missile tests, the resolution imposes an arms embargo on the transfer of major weapons systems to Iran.
June 24, 2010: Congress adopts the Comprehensive Iran Sanctions, Accountability, and Divestment Act; tightening U.S. sanctions against firms investing in Iran’s energy sector, extending those sanctions until 2016, and imposing new sanctions on companies that sell refined petroleum to Iran.
July 26, 2010: The EU agrees to further sanctions against Iran. A statement issued by EU member state foreign ministers refers to the new sanctions as “a comprehensive and robust package of measures in the areas of trade, financial services, energy, [and] transport, as well as additional designations for [a] visa ban and asset freeze.

September 27, 2018: In his address to the UN General Assembly, Israeli Prime Minister Benjamin Netanyahu reveals what he describes as a secret nuclear warehouse “storing massive amounts of equipment and material from Iran’s secret nuclear weapons program.” Netanyahu also called on the International Atomic Energy Agency (IAEA) Director General Yukiya Amano to “do the right thing” and inspect the warehouse “immediately” before Iran finished clearing it out. He charged that Iran removed 15 kilograms of radioactive material from the warehouse in August, but did not specify if the material was uranium, plutonium, or another radioactive source. One intelligence official quoted in Reuters says that the facility has been known to the U.S. intelligence community for some time and it is full of documents, not nuclear equipment. The official says that “so far as anyone knows, there is nothing in it that would allow Iran to break out” of the nuclear deal any faster.
October 2, 2018: IAEA Director-General Yukiya Amano says in a statement that the agency does not take any information at “face value.” While Amano did not mention Netanyahu directly, he said that all material, including that received from third parties, is subject to a rigorous and independent assessment. Amano said the IAEA’s nuclear verification work “must always be impartial, factual, and professional” and that the agency’s independence is “of paramount importance.”
October 3, 2018: The International Court of Justice (ICJ) rules unanimously that the United States “must remove, by means of its choosing, any impediments” to the export of food, agricultural products, medicine, aircraft parts, and other humanitarian goods. The 15-member panel concludes that Trump’s decision to reimpose sanctions on Iran was unfounded given Tehran’s compliance with the JCPOA, but the court did not order the United States to remove all sanctions or compensate Iran for damages.
November 5, 2018: The second round of sanctions on Iran following Trump’s withdrawal from the JCPOA, targeting Iran’s banking, oil, shipping and ship-building sectors, come back into effect.

January 29, 2019: The annual Worldwide Threat Assessment of the U.S. Intelligence Community assesses that “Iran is not currently undertaking the key nuclear weapons-development activities we judge necessary to produce a nuclear device.” It adds that “Iran’s continued implementation of the JCPOA has extended the amount of time Iran would need to produce enough fissile material for a nuclear weapon from a few months to about one year.”
January 30, 2019: IAEA Director-General Yukiya Amano reiterates that Iran is implementing its nuclear-related obligations under the JCPOA and states that attempts to “micro-manage or put pressure on the agency in nuclear verification” are “counter-productive and extremely harmful” in remarks to the IAEA staff. Although Amano doesn’t name who was putting pressure on the agency, he is likely referencing Israeli and U.S. efforts to persuade the IAEA to investigate what they deem a “secret atomic warehouse” in Iran, which Israeli Prime Minister Benjamin Netanyahu described in his September UN General Assembly speech.

November 24, 2021: Speaking to reporters in Vienna, IAEA Director General Rafael Grossi says that although talks in Tehran were “constructive” they were “inconclusive” in resolving the dispute between the Agency and Iran over access to the Karaj centrifuge component manufacturing facility. The IAEA is close to the point where the Agency would “not be able to guarantee continuity of knowledge” with respect to Iran’s nuclear activities, he concludes.
A meeting of the IAEA’s Board of Governors meeting begins, in virtual format. In his statement to the Board, Grossi saysthat “the lack of access to the Karaj workshop has meant that restoration of surveillance and monitoring at all of Iran’s facilities and locations in relation the JCPOA could not be completed.” Grossi warns that the ongoing dispute over access to monitor Iran’s nuclear activities at Karaj “is seriously affecting the Agency’s ability to restore continuity of knowledge at the workshop, which has been widely recognized as essential in relation to a return to the JCPOA.”
Iranian Foreign Minister Hossein Amirabdollahian tweets that talks in Vienna were “cordial, frank [and] fruitful.” He writes that “to work out a text, we need work on a few words,” adding that “agreement is possible” and that another meeting between Iran and the IAEA will be held soon.
